How old is your configuration? Do you get any error code or error message after the crash, you can view that in event manager as well? What is the model number of the nvidia graphic card that you are using? I can see that you have a prescott processor but which motherboard are you using? Also, it would be good if you can tell us which Power supply is installed in your computer? Usually, it sure seems to be a overheating problem and therefore, you will have to either fit a cpu cooler in your pc or apply some thermal paste on your CPU. You can also monitor your computer temperature by using a utility called CPU temp while gaming.

umm the only one around that time thats not a windows update log is this:IRQARB: ACPI BIOS does not contain an IRQ for the device in PCI slot 2, function 0. Please contact your system vendor for technical assistance.

Alright, what i meant about configuration was only asking you to give us your computer specifications in details, like what motherboard, power supply, processor, etc. For power supply information, you will have to remove your computer case from left side and then check how much Watts it is. Also, if you are so unsure about anything, then I recommend you to ask any computer vendor to come at your place and check for problems, specially overheating problems.
